[Class 52 (iv).] A self - supporting spring cushion or like upholstered article consists of rows of upright spiral springs the upper and lower coils of which overlap, and the adjacent springs are held together by wires which are passed through the opening formed by the overlapping coils and are bound at both ends round the coils at the crossing-points so as to form a hinge, enabling the cushion &c. to be readily folded or rolled., Fig. 1 shows the device in plan, and Fig. 4 is an elevation of the hinge joint. The springs are of double conical form, and their large uppermost and lowermost coils 10 are arranged to overlap each other as regards their transverse neighbours, but may be free of their longitudinal neighbours. Where the overlapping coils 10 cross, a wire 13 is first given one or more turns around the coils, is then passed through the narrow opening between the coils, and then given one or more turns round the coils at their other crossing point. This forms a hinge which tends to restore the springs to normal position after flexing. Each coil may be linked to its longitudinal neighbour by binding the end 11 of each coil round the next coil. The lower ends of the coils are similarly connected.

Title: Image analyser
IPC: H01J31/50
Filed: 1974-06-25
Abstract: 1471624 Image pick-up tube PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 25 June 1974 [28 June 1973] 28111/74 Heading H1D An integrating image pick-up tube providing a video output signal without electron beam scanning comprises envelope 1 holding a conductive first photocathode 7 sensitive to incident radiation focussed 50 through face plate 3, a reversible channel multiplier 9 and, a second low conductivity photocathode 17 acting temporarily in the "write-in" first phase as a collector, assembled in target 15 on a transparent electrode 21, separated therefrom by a transparent dielectric (e.g. mica). Initially layer 17 is at the same potential as electrode 21, the potential rising from photocathode 7 through the multiplier 9 to photocathode 17 (Fig. 2, not shown); after exposure a negative  going charge image, intensified by multiplier 9, is built upon layer 17. The potential gradient is then reversed for the "read-out" second phase and target 15 is illuminated from the rear, layer 17 now acting as a photocathode and first photocathode 7 becomes a collector; the charge on the elements of 17 is read-out by scanning the rear with a spot or strip of light 37, causing each element in turn to supply a current, intensified by multiplier 9 now working in the reverse direction; for collection by layer 7, giving a video output signal across resistor 55. The elements of layer 17 are left ready for the next cycle. Imaging in the read-out phase is not necessary and the electron stream may be deliberately dispersed by an A.C. magnetic or electric field between plate 13 and photocathode 17. The first photocathode 7 is a good conductor, with sensitivity matched to the incident radiation, while the second 17 must be poor, being either a homogeneous layer of poor conductor or a mosaic of conductor as deposited or converted from a homogeneous layer. The wavelength of the scanning light is matched to the sensitivity of the second photocathode. If the image is a line spectrum the elements of the second photocathode 17 may be horizontal insulated stripes as shown, scanned vertically by a tangental strip of light, from tilting mirror 48; several orders of the spectrum may lie side by side, scanned vertically in turn by a short strip of light, the elements of photocathode 17 being segmented stripes. First photocathode 7 may alternatively lie against channel amplifier end 11, and target 15 may alternatively lie against rear face plate 5.

Title: Improvements relating to filters
IPC: B01D35/147
Filed: 1938-09-28
Abstract: 520,779. Filters. VOKES, C. G. Sept. 28, 1938. No. 28225. [Class 46]. In filters, such as described in Specification 470,536. provided with a hollow filter element which moves to allow the liquid to bye-passthe element when the filter pressure rises above a predetermined limit, provision is made for preventing the passage of unfiltered liquid, when the rise of pressure is due to increased viscosity of the liquid. The invention is applicable for lubricating system filters where the oil is cold when the engine is started. Fig. 1 shows a hollow filter element 1, the end plate 4 of which is normally held against an inlet tube 5 by a spring 3. Increase of pressure on the inlet side of the filter forces the element down against the spring 3 and allows liquid to bye-pass from the tube 5 to the outside of the element. A plunger 9 screwing through a plug 8 in the bottom of the casing can be raised so that its head contacts with the lower end of the element and prevents it from moving down to allow the liquid to bye-pass. As shown in Fig. 2, the plunger 14 slides through a plug 16 and is normally held up by a spring 17 to prevent byepassing, but can be run down to the position shown and turned so that it is held there by a pin 19. Means for preventing bye-passing can be automatically controlled; for example, an  electrically or mechanically operated bolt or stop may be controlled by a viscosity meter. Fig. 3 shows an arrangement for automatic control of the bye-pass in accordance with the temperature of the liquid. The bye-pass may be left closed by an. auxiliary spring 23 acting through a member 27. Thermo-cells 22, arranged with the spring 23 in a frame 24, press downwardly on the member 27 when the temperature rises, so that the filter element can then move downwardly to open the bye-pass if the pressure of the liquid rises sufficiently to overcome the spring 3. Fig. 4 shows apparatus with a coarse filter 30 through which the liquid passes when the bye-pass is opened.

Filed: 1932-04-22
Abstract: Cellulose esters or ethers, dyeing; printing.--The fixation on materials made of or containing cellulose esters or ethers, of suspensions or dispersions of colouring matters having affinity therefor, is effected with the aid of a di- or poly-alkylene glycol or an ether, ester or ether-ester thereof, followed by a steaming of the dyed material, processes involving a reduction of the dyestuff on the material being excluded.  As a modification the di- or poly-alkylene glycols or their derivatives may be replaced by the corresponding compounds in which an ether oxygen p  atom is replaced by an atom of sulphur.  Specified compounds used are di- and tri-ethylene glycols, di-glycerol, diethylene glycol monoacetate, the acetate of diethylene glycol monoethyl ether and thiodiglycol. Relustring of a delustred fabric may be effected by the steaming. Printing preparations containing the colouring matters and the di- or poly-alkylene glycols or their derivatives may contain in addition solvents, swelling agents or assistants such as ethyl lactate, hydroquinone, urea, aliphatic alcohols, phenols, diacetone alcohol, diethyl or dibutyl tartrate or benzyl alcohol.  In an example, a cellulose acetate woven fabric is printed with an aqueous composition containing the dyestuff 1 : 4-di-(methylamino)-anthraquinone, gum arabic and diethylene glycol, and the print is dried, steamed, washed, and dried to obtain a brilliant blue pattern.

Abstract: 1408705 Seismic energy generators TEXACO DEVELOPMENT CORP 15 June 1973 28498/73 Heading H4D A seismic energy generator of the compressed gas gun type for use underwater is constructed so as substantially to eliminate secondary bubble-oscillation energy and comprises a piston which uncovers a discharge part to release gas abruptly from a cylindrical chamber, the ratio of the port's cross-sectional dimensions in the circumferential and axial directions of the chamber, respectively, being at least three to one. In the embodiment shown, with the gun in its charged state, a compressed air charge is retained in chamber 11 by a piston valve 57 which is held against a sprung valve seat 35 by a pressure differential acting on its upper and lower faces. The pressure on the upper face of piston 57 is maintained in an auxiliary chamber 67 by an auxiliary piston valve 72, itself held in the closed position by a differential pressure. To fire the gun, a solenoid valve 88 is actuated to reduce the pressure above piston 72 which then moves up to exhaust gas from chamber 67 into exhaust chambers 74 (and thence via check valves 126 into the water). Piston 57 then moves up to release the main air charge from chamber 11 via radially-directed ports 61 into the water to generate the seismic pulse. The ports have a cross-section as specified above: this, together with the fact that the sprung valve seat 35 enables an abrupt opening of ports 61, gives the desired bubble characteristic.
